Specification of Letters Patent.

Patented Nov. 23, 1%;5.

Application filed March 16, 1914, Serial No. 824,98?! Renewed. June 11, 1915. Serial No. 33,625.

To all whom it may concern:

Be it known that I, THOMAS B. JARvIEs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in VVater- Heaters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and use the same, reference being had to the accompanying drawings, and tothe letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to water heaters, and more particularly to a device of that character for use in connection with upright boilers of the type ordinarily used in residences; the principal object of the present invention being to provide a heater wherein the flow of water from and to the boiler is retarded to increase the heating period, and obviate the drawing of water directly from the heater instead of from the boiler.

It is also an object of the invention to provide the improved details of structure hereinafter described and illustrated in the accompanying drawings, wherein Figure I is a perspective view of a water heater constructed according to my invention, showing its combination with a boiler, and wherein a portion of the heater is broken away to illustrate the retarder. Fig. 11 is an enlarged longitudinal section of the retarder.

Referring more in detail to the parts: 1 designates an ordinary upright boiler of the type particularly adapted for domestic use, and having intake and outlet pipes 2-3 opening into its upper end, and a feed pipe 4 leading from its lower portion to the heater.

Leading vertically from the pipe 4 is a connecting pipe 5, and mounted on the pipe 5 is a heater section 6, which is preferably composed of cast metal and comprises a series of bells 7, each comprising an integral, inverted and upright conical section, forming a center, and upper and lower neck portions of relatively large andsmall diameter, with the upper and lower necks of each bell connected with like necks on adjacent bells, so that water may flow entirely through the heater section, but may have ample opporback through the tunity to become heated during its travel, on account of the large heating area provided by the cone-shaped bells.

The upper bell 7 is provided, at its central point, that is, at the meeting point of its inverted and upright conical halves, with an outstanding flange 9, whlch serves to retard the flow of heated air along the section 6 and deflect the same back to contact with the walls of the heater, in order to secure the greatest possible efficiency; the entire heating section being inclosed in a casing 10, so that the heated air from a burner 13, which is preferably located at the bottom of the casing, may be confined about the heating section.

A flue 14: opens from the top of the drum to carry off the non-combustible gases and provide sufiicient draft for proper combustion of the fuel, and a pipe 15 leads from the top of the heater section to the outlet pipe 3, so that water may pass from the boiler through the pipe 4 to the heater, and pipe 15 and outlet pipe 3 to the top of the boiler.

In order to retard circulation through the heater, I provide the latter with a diaphragm 17, which I preferably locate in the neck 8 that separates the two upper bells 7, and provide said diaphragm with a relatively small aperture 19. A ball 20 is located within the upper bell 7 and adapted for seating over the aperture 19 to retard the flow of water therethrough.

In using the device, presuming the parts to be constructed and assembled as described, with the burner in operation and the boiler filled with water, heat from the burner pass ing through the drum contacts the heating section 6 and raises the temperature of the water contained therein, so that a circulation is established between the boiler and heater through the pipes 4t, 15 and 3.

The weight of the ball valve in the upper bell causes the same to seat over the aperture 19 in the diaphragm 17, so that it retards the circulation sufliciently to retain water within the heating section until its temperature has been raised sufliciently to generate power enough to displace the ball when the latter is removed from its seat by the buoyancy of the water contained within the lower bells, and this heated water passes on through the circulating pipe to return to the boiler; the process being continuous when suflicient heat is delivered into the heater shell.

A further advantage gained by the use of a heater of this construction lies in the fact that the Weight of the ball valve is sufiicient to insure against the withdrawal of Water from the heating section and pipe 15 directly to the outlet pipe 3, when the pipe 3 is tapped; the retarding of the How by the ball valve being sufficient to insure the withdrawal of water-16mm the boiler, rather than from the heater pipe. H V 7 Having thus described my invention, what I claim as newtherein, and desire to secure Letters-Patenn-is: y y

1. The combinationvwith circulation pipes of aheater comprising bell members having a valved port for establishing communica- "tion therebetween, and a valve for automatically closing said port.

V 2. The combination with circulation pipes 'of 'a heater 'comprisingbell members having a valved port for establishing communication therebet'ween, a valve for automatically closing said port, a drum inclo'sing the bell members, and means for heating the interior of the "drum. I p

' I 3. The combination with circulation pipes oif'a heater comprising bell members having a valved port for establishing communicat 'ti'on 'therebetWeen', a valve for automatically closing saidport, a drum inclosing the bell members, means for heating the interior of the drum, and a flange on one of the bell members for retarding the flow of heated air through the drum.

' 4. The combination with circulation pipes, of a heating section connected with said pipes, and comprising a plurality of bells having a restricted connection provided with a valve port, and a valve member adapted for automatically closing said port.

5. The combination with circulation pipes, of a heating member having its opposite ends connected with said pipes and comprising a plurality of bells having restricted necks for establishing communication therebetween, a diaphragm closing one of said necks and provided with a valve port, and a ball valve located in the upper bell and adapted for closing said port.

6. In a water heater, the combination with a reservoir having a supply pipe, an outlet pipe for-said reservoir, and a circulating pipe communicating with said reservoir and with said outlet-pipe, of a heater interposed in said circulating pipe and having a restricted passage for checking the flow therethrough when said outlet pipe is open.

7. In a water heater, the combination with a reservoir having an inlet pipe, an outlet pipe opening from the top of said reservoir, and a circulating pipe connecting with the base of said reservoir and with the outlet pipe, of a heater interposed in said circulating pipe comprising a plurality of bells having a restricted connection provided with a valved port, and a. valve member for automatically closing said port and checking the flow through the heater When the outlet pipe is opened.

In testimony whereof I a'lfix my signature in presence of two witnesses.
